To zZZ whom t mag/concern.'

Be it vknown that I, OSCAR E. BUnnI-roLDER,

- a citizen of the United States, residing in the city and county ofvSan'V Francisco and StateV of California, have invented a new and usej ful `Improvement in the following is a full, clear, and exact scription, such as will enable others skilled g Securing-Pins, of which in the art to which it appertains to make and use the same.

My invention relates to improvements in securing pins of the type used for hair pins, hat pins and other similaiarticles, wherein a pair of pins operate in conjunction with a ypair of tubular members, connected at one end, to inclose material fastened.

The primary object of the present inven- "tion is to provide an improved hair pin or hat pin'.

-A further object of the invention is to provide a pair oftubular members connected at one end to form a yoke and to move a pair of pins through the legs of said yoke to cross -each other'when projected beyondthe free ends of said yoke to inclose material'being fastened therein.

l accomplish these andV other objects by means of the device disclosed in the drawings forming a part of the present specification, wherein like characters of reference are used to designate similar parts throughout the said specification and drawings, ln which- Figure l is an enlarged improved securing pin;

Fig. 2 is a further enlarged broken, secdisclosing the means for preventelevation of my tional view ing the withdrawal of the pins from the tubular member; and n Fig. 3 is also a further enlarged broken sectional view disclosing the manner in which the course or direction of the pins are changed when projected from the tubular members. Y

Referring to the drawings the numeral 1 is used to designate a pair of tubular members connected at one end as at 3 and provided with coaxial apertures l adjacent said connected ends. Y

The free ends of the members l are curved inwardly on their outer surfaces as at 6 and provided with a second set of apertures 7 on the inner surfaces of said ends which are pointed to facilitate passage through fabric, hair and the like.

A pair of pins 8 are specification oriettersv Patent.

vslidably mounted Patented Apr. 5, 1921.

Application filed. January 2D, 1'92. Serial No. 353,086.

within the tubular membersl and extend through the apertures 4L at the connected ends of said'tubularmembers, said pins 8 be ing also connected as at 9 eXteriorly of said connected ends of the tubular members l.

The pins 8 are `provided with suitable pro-v jections l0 by means of a bent offset or any other suitable means to provide an obstruction adapted to prevent the passage of said pins 8 through the apertures 4f of the members l whereby the entire withdrawal of said pins from the tubular members 8 may be prevented.

In operation the members l, with the pins 8 receded, are passed through the material to -be secured, as a ladys hat' or hair, and

after being placed inwardly as far as possible, such as placing a hair pin or the like,

the `pins 8 are projected throughfthe apertures 7 adjacent the free ends ofthe members 1, the curved surfaces 6 operating to change 'the course of said pins 8 as they are projected and. cause said pins to cross `each "other when projected fully beyond said free ends, as disclosed in dotted lines inFig. l of the'drawings. y c

In this-manner material betweenthe tubu` lar members l will be inclosed by said members and the crossed ends of the pins 8.

The pins 8 are suiiiciently rigid to normally retain such material in position and thereby normally prevent withdrawal of the device.

To remove the device the pins 8, by means of their connected ends as at 9, are receded into the tubular members l until the projections 10 thereon engage the connected ends of said tubular members thereby preventing further movement of the pins.

Having thus ,described my invention what I claim as new and desire to secure by Letters Patent is Y l. A securing pin comprising a pairvof tubular members connected at one end and having the outer surfaces of the opposite ends curved inwardly and apertured; and a pair of pins slidably mounted within the tubular members and arranged to be moved by said curved ends to cross each other when projected beyond said ends.

2. A securing pin comprising a pair of tubular members connected at one end and having the outer surfaces of the opposite ends curved inwardly and apertured, a pair of pins slidably mounted within the tubular members and arranged to be moved by said curved ends to cross'each other when projected beyond said ends; and means for preventing withdrawal of the pins from the opposite ends of said tubular members.

3. A securing pin comprising'a jpair of tubular members connected at one end and Shaving the-ir opposite ends pointed and curved inwardly on their surfaces and japer` tures onY their inner surfaces adjacent said curved ends; a pair of pins slidably mounted within the tubular members and arranged to be moved by the, curvedends of said members to cross each other when proi jected beyond said curved ends.

A, A securing pin comprising a pair of tubular members connected at one'end and having their vopposite ends pointed and curved inwardly on their outer surfaces. and

apertures on their inner surfaces adjacent said curved ends; a pair of pms shdably Y mount-ed within the tubular members and connected exteriorly of the connected endsy of said tubular members and arranged to be'moved bythe curved ends 0f said mem.-

bers to cross each other when projected beyond said curvedends; and means for preventing withdrawal of said pins from the connected ends of said tubular members.

5. A securing pin comprising a pair of tubular members connected at one end and provided with curved outer surfaces at their Vopposite ends and aperturesrarranged on vthe inner surfaces and adjacent said ends,

and likewise having a second set of aper- Y tures registering coaxially with. said tubular members adjacent their connected ends;

Y jacent the curved signature.

and aV pair of pins slidably mounted within the tubular membersand connected adjacent the connected ends of the tubular members eXteriorly thereof and also arranged to'be moved to cross each other by the curved` surfaces of the opposite ends 0f the tubular members when said pins are projected 'throughy the apertures adjacent said ends ;V and pins slidably mounted within the tubular members and projecting'through the apertures; at the connected end of said member and connected eXteriorly thereof,

said pins being moved t0 cross each other when projected throuo'hY the apertures adends and likewise provided with project-ions within the tubular members, said projections*engaging the tubular members adjacent Y the apertures thereof adjacent the connected Vends whenl receded the tubular members to prevent entire withdrawal of said pins from said tubu-V lar members.

In witness whereof I hereunto set my OSCAR E. BURKHLDER.
